CULVERT LINING.

Application filed November 10. 1922.

To all wlw/1L t 'may concern:

Be it known that I, Annnnn'r Ausruf. a citizen of they United States,residing at Greenwood, in the county of Steuben and State of New York,have inventcd'certain new and useful Improven'ientsin Culver-t Linings,of which the following is a speci.- -ticationl f' This invention relatesto an improved ,lining for road culverts or the like and seeks. as oneof its principal ohjectato providel a lining so constructed that, when aculvert becomes choked with sand, mud orgravel. the lining may he'removed to clear the cul vert, thus dispensing' with the necessity formanually digging the clogging substance .from the culvert.

A further object of the invention is to provide a lining composed of aplurality of mating units and wherein the units may he drawn from theculvert one hy one for carrying the deposits from the culvert.

And the invention has as a still further object to provide a liningwherein the units will he so constructed that in the operation ofcleaning a culvert, the material in the units will he retained therein.during withdrawal of the units.

Other and incidental objects will appear hereinafter. l

In the drawings:

Figure 1 is a vertical sectional view showing my improved lining inconjunction with a conventional road culvert.

Figure 2 is a horizontal sectional view more particularly illustratingthe structure of the lining, and

Figure 3 is a detail perspective view showing one of the lining units.

In carrying the lnvention into eiiect. I employ a plurality of channelshaped lining` units or trays 10. These units may he formed fromsuitable resilient sheet metal heut to the desired shape and, as clearlyhrought out in Figures 2 and 3. the units are tapered in widthlongitudinally thereof so that the upstanding side walls of the unitsgradually converge toward the rear ends of the units. Riveted orotherwise secured to said side walls at the forward ends of the unitsare loops 11. In some instances, it may be found desirable to cast theunits, in which event the loops ll'may be integrally formed on the sidewalls of the units, and where the size of the units would render SerialN0.y 600.105.

the units too heavy to he conveniently handled or transported, the unitsmay he split longitudinally into mating sections.

ln Figures l and Q of the drawings, I have. l'or convenience, shown myimproved lining in conjunction with a conventional road culvert l2.

culvert to extend from one end ofthe culvert to the other and are shapedto conform to the contour of the culvert, it being, of course.understood in this connection, that in any instance where a c vlindricalculvert is to he equipped with the lining. the units of the lining will.he shaped accordingly. The units are arranged to ahnt 'each other sothat the 'Hat hottom walls of said units will form a continuous surfaceat the bottom of the culvert and, as will be noted, the side walls ofthe units at the smaller ends thereof are disposed to fit between theloops ll at the larger ends of the units, while the larger ends of theunits are of a Width to quite snugly tit hetween the side walls of theculvert. Thus. water may freely How through the lining and. of course,as sediment is deposited within the culvert, such sediment will hecontained within the lining. Accordingly, when the culvert becomesclogged. the lining may he removed for cleaning the culvert. Tofacilitate this operation, I provide a hail 13 which is formed mediallvwith an eve l-it and equipped at its ends with hooks 15 freelyengagealole in the' loops of the units of the lining. Thus, as suggestedin Figure 2. the hail may be engaged with the terminal unit at one endof the culvert. when a draft animal may loe hitched to the hail as h v achain or other device. and the unit pulled from the culvert. After theterminal unit has heen so withdrawn. the next unit may vthen hewithdrawn and so on until all of the units have heen removed. In thisconnection. attention is directed to the fact that due to theinclination of the side walls of the units. the material in the unitswill he prevented from discharging therefrom as the units are withdrawn.Asi' will he seen. any rearward slipping of the material in the unitsduring the withdrawal ofthe units will serve to jam or pack the materialhetween said side walls so that thc units cannot he caused to slipforwardly Jfrom heneath the material contained therein nor can the ma-.\s will he observed, the -unlts are arranged `end to end within theterial in the units slide hackwardly out. of the units. Afterthe unitshave been displaced, theunits may, of course, be readily dumped andcleaned so that the entire operation of cleaning the culvert may beeasily and quickl f accomplished.

In the oregoing' description, I have referred to the invention as aculvert lining and have so illustrated the structure. However, as Willbe perceived, the invention is alsoapplicahle for use., in connectionWith open ditches or other conduits and the term culvert as herein used,is, therefore. in-v tended vto cover such 4adaptations of the invention.K

Having thus described vthe is claimed as new is:`

l. The combination with a culvert or the like, of a lining freelyreceived in the culvert. and removable foecleaning the culvert ofsediment. deposited in the lining.

Q. The combination with a culvert or the like. of a liningI for theculvert composed of a plurality of mating units separately removable forcleaning the culvert of sediment deposited in the, lining. n

3. In a culvert, the comhinationof a conduitl` and a liningY arrangedWithin the conduit and composed of a plurality of mating units slidablyfitting in theconduit and separately removable therefrom for cleaningthe culvert of sediment deposited in the lining.

4. A culvert lining including' a plurality of lining' units freelyinsertahle in a culvert. to mate therein, forming;` a removable lining,Yfor the culvert.
